I needed to make a 31 tooth gear and no 31 or 62 circle available on my dividing plates so I went the Gingery route and drilled a 62 circle in a spare space on one of my dividing plates. Cut a strip of paper the width of your plate, longer than the circumference of the plate. Tape one end on the outside of the plate and wrap it around the plate. Pull tight and cut through both thicknesses with a razor knife. You now have a strip the exact circumference of the plate. Lightly tape the ends on a piece of drawing paper and take a line from one end down at about 30 degrees and use dividers to step off 71 spaces so that the 71st is somewhere below the other end of the strip.

You need two set squares with one joining the end of the strip and the 71st line. Maintain that angle and strike off your 71 spaces. They will go from 0 to 71.

My method was to tape the strip to the plate and mount it in the lathe and use a dremmel mounted in the toolpost to drill the holes and have a solidly mounted pointer and bring each line to it and drill for each mark. Worked for me. Machinery's Handbook has charts for compound indexing. This is a method of using two different hole circles on one plate, to arrive at a very close approximation of the required number of divisions. It would be preferable to make a plate with 71 holes, and you might be able to fit it on a 5' hole plate. This keeps things simple while you cut the gear. If you screw up making the plate over a time or two, it won't be so hard to bear.

Use the sector to help count 4 turns and 25 (spaces) in the 39 hole circle with the crank pin. Then, withdraw the pin on the back of the plate (which should be kept in the 41 hole circle) and count an additional 2 turns and 28 (spaces) on the 41 hole circle. Let the crank ride fixed into the plate while you turn the latter amount.
